Solution 1

Hi,

For each table in your dataset, try the following code:

C#

string valuesarr = string.Empty;
for (int i = 0; i < dt.Rows.Count - 1; i++)
{
   List<object> lst = dt.Rows[i].ItemArray.ToList();
   foreach (Object s in lst)
   {
       valuesarr += s.ToString();
   }

if (String.IsNullOrEmpty(valuesarr))
    dt.Rows.RemoveAt(i);
}
dt.AcceptChanges();

Hope this works for you :)

Regards,
Praneet

Solution 3

Linq Query has solved my problem.

C#

dt.Rows.Cast<DataRow>().Where(rows+>!row.ItemArray.all(field =>field is System.DBNull || String.compare((field as String.Trim(),String.Empty)==0)).CopytoDatatable();
